In my opinion, no risk no reward and the more the risk the more the reward. When it comes to dealing with top 100 cryptocurrencies, it actually does not matter how risky it can get or not because even the top 100 cryptocurrencies have high risk too when buying and selling. On the other hand, the cryptocurrencies that are not listed in the top 100 coins, despite the high risks involved can give one a mind blowing profit that can not be achieved in the in a short while in the top 100 cryptocurrencies.
